Physical education plays a vital role in the students' development and growth. According to recent medical studies, physical well-being of a student is directly related to his or her performance whether in class or in the office. {#blank#}1{#/blank#}

It's a link to good health.

    {#blank#}2{#/blank#} It's only in physical educational classrooms that students learn the value of taking care of themselves through proper grooming, healthy eating and regular exercise.

    Many doctors today agree that obesity is a serious health risk. Without any form of diet management and control with the numerous processed food students intake every day, a student's health can easily be at risk to many diseases. Physical education in school is a preventive measure to teach students the value of regular exercise.

It promotes academic learning.

    Physical health allows students to function better in classrooms. A good cardiovascular system developed from regular exercise promotes excellent blood and oxygen circulation. {#blank#}4{#/blank#} This circulation produces longer attention span during classes allowing longer concentration and absorption.

It builds self-trust.

    Students who are active in physical activities are more confident with themselves according to most social school studies. It's probably because of the self-discipline and dedication to excel in a sport that brings out the best in students. In school, the physical education program introduces these sport activities to students. {#blank#}5{#/blank#}

It promotes a physically active lifestyle.

    The purpose of physical education is to instill in students, at an early age, the value of self-preservation and choosing a lifestyle that is good for both the mind and body.

The Lost Rules of Etiquette

    Etiquette, or good manners, used to be the glue that held society together{#blank#}1{#/blank#}Sadly, these days it has mostly gone by the wayside. This list is several best rules of etiquette that have now disappeared.

Opening the Door

    In days gone by, a gentleman would always open doors for ladies{#blank#}2{#/blank#}This has now almost entirely disappeared-- and it is pot entirely the fault of the men. I have seen women laugh at men for opening a door for them. They seem to be confusing manners with chauvinism(大男子主义)．

Writing Thank-You Notes

    In days gone by, whenever a person received a gift, they would write a thank-you note as soon as possible{#blank#}3{#/blank#}Parents would sit children down after a birthday or Christmas and coach them in their first thank-you note. It is a shame that gift giving has now become a virtual obligation and the idea of a thank-you note would be laughed at.
{#blank#}4{#/blank#}
         We seem to have completely lost the concept of correct timing when it comes to parties these days{#blank#}5{#/blank#} After all, a party normally has a guest of honor-this is usually the oldest woman present. It was considered extremely rude in the past to leave a party before the guest of honor-and once the guest of honor left, it was a signal to all that they should begin their own preparations to leave.

A. Arriving on Time.

B. Leaving at the Right Time.

C. People leave with various excuses.

D. It enabled people to get on well with each other.

E. This rule was true even if the giver was a relative.

F. It could be the lady they were driving, or a stranger.

G. We've thrown away the concept of a guest of honor at will.

Ways to protect eyes from screens

    Too much screen time may cause serious eye strain(眼疲劳) and even a sharp decline of eyesight. That's a big problem a lot of people are faced with nowadays, especially those who work on a computer. The following tips may be helpful.

Get regular eye tests.

    Experts recommend having a comprehensive eye exam every year to detect (探测) problems before they develop. During this test, you should tell the doctor how often you use your phone and your computer. {#blank#}1{#/blank#}Tell your doctor about it, and your eyes can be tested more accurately at that distance.

Give your eyes space

     {#blank#}2{#/blank#} Studies on computer-related eye strain suggest that screens should be no closer than 40cm from your face. If this makes it hard for you to read, consider increasing the size of the text rather than moving the screen closer.

Take breaks

    This may not always be practical if you're quite busy, but it's important not to stare directly at a screen for too long.  {#blank#}3{#/blank#} While surveys have shown that many office workers take no more than half an hour a day away from their computer, it's recommended that you take a 15-minute break after every two hours spent at your screen.

     {#blank#}4{#/blank#}

    Staring at a screen continuously for hours on end may make it difficult for you to focus. To avoid this, many eye experts recommend the “20-20-20 rule” --looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20 feet away for at least 20 seconds. The science behind his trick is that looking at objects at a distance relaxes the focusing muscle in the eye.  {#blank#}5{#/blank#}.

    Patrick and Rachel Hugens have biked around the world. The Hugenses, who live in Boise when not on their bikes, are 25 months into their latest round-the-world adventure, scheduled to end in March. They've visited 36 countries on this tour, touching Europe, Africa, Asia and South America. “Traveling by bike is the greatest freedom," Rachel said via email. “You can see people's daily lives and can communicate with them.”

    Rachel warns, “Cycle touring can become addictive.” Bike tourism is on the rise in the United States and around the world, according to the Adventure Cycling Association. The U. S. Bicycle Route System has grown 66 percent in the past two years and now has a presence in 24 states, including Idaho, and the District of Columbia.

    Dennis Swift，secretary of the Southwest Idaho Mountain Biking Association, rode across the U.S. last year- from Seattle to Salem, Mass. Six people started the tour and three finished, riding 52 out of 56 days. They averaged about 60 miles per riding day. Swift also rode through the Basque Country with a group of Boise cyclists last year. He's planning to participate in a Virginia bike tour this year. “When you get older, your health is most important,” he said. “My mom had Alzheimer's disease. They say what's good for health is good for the brain, so riding is one thing to be first in my life.”

    This is the third time that the couple have quit their jobs to tour. Rachel is a nurse; Patrick is an architect. Both regained their former jobs when they returned home in 2000 and 2007. They're uncertain what will happen this time. They've given themselves a chance to save extra money by going to work by bike and avoiding some bills that are basic for most (cell phones, cable TV).“Traveling changes your view of money and what it can do for you,” Rachel said. “We've met some cyclists traveling long term. They have many reasons to spend wisely.”

    “The fellow cyclists we meet mostly come from Britain, Germany, Spain, Holland, Australia or New Zealand," Rachel said, “It is so nice to see that people all over the world are friendly and welcoming.”
